The name 'Eagle' was used by Rolls-Royce for a number of engines, most famously the first, the Eagle V12 aero engine developed during the First World War, and used to power a number of military aircraft.
The first Eagle aero engine was a liquid cooled V12 engine with the cylinders inclined at 60 degrees and the valves driven by overhead camshafts. It first ran in 1915. Bore and stroke were 4.5 inches by 6.5 inches (115 x 165 mm) giving a 20 litre capacity. The whole engine weighed 408 kg (900 lb) producing 360 hp (268 kW) at 1,800 rpm.
Production ran until 1928 by which point 4,681 had been built.
There is an example of this engine in the London Science Museum.
